Bits 17:15 – FCNT[2:0] The number of frames per sub-buffer for synchronous channels

ValueNameDescription
0 1_FRAME 1 frame per sub-buffer (Operation is the same as Standard mode.)
1 2_FRAMES 2 frames per sub-buffer
2 4_FRAMES 4 frames per sub-buffer
3 8_FRAMES 8 frames per sub-buffer
4 16_FRAMES 16 frames per sub-buffer
5 32_FRAMES 32 frames per sub-buffer
6 64_FRAMES 64 frames per sub-buffer

Bit 14 – CTLRETRY Control Tx Packet Retry

ValueDescription
0 A control packet that is flagged with a Break or ProtocolError by the receiver is skipped.
1 A control packet that is flagged with a Break or ProtocolError by the receiver is retransmitted.

Bit 12 – ASYRETRY Asynchronous Tx Packet Retry

ValueDescription
0 An asynchronous packet that is flagged with a Break or ProtocolError by the receiver is skipped.
1 An asynchronous packet that is flagged with a Break or ProtocolError by the receiver is retransmitted.

Bit 7 – MLBLK MediaLB Lock Status (read-only)

ValueDescription
0 Indicates that the MediaLB block is not synchronized to the incoming MediaLB frame.
1 Indicates that the MediaLB block is synchronized to the incoming MediaLB frame.
  • If MLBLK is cleared (unlocked), MLBLK is set after FRAMESYNC is detected at the same position for three consecutive frames
  • If MLBLK is set (locked), MLBLK is cleared after not receiving FRAMESYNC at the expected time for two consecutive frames. While MLBLK is set, FRAMESYNC patterns occurring at locations other than the expected one are ignored.

Bit 5 – ZERO Must be Written to 0

Bits 4:2 – MLBCLK[2:0] MLBCLK (MediaLB clock) Speed Select

ValueNameDescription
0 256_FS 256xFs (for MLBPEN = 0)
1 512_FS 512xFs (for MLBPEN = 0)
2 1024_FS 1024xFs (for MLBPEN = 0)
3 2048_FS 2048xFs (for MLBPEN = 0)
4 3072_FS 3072xFs (for MLBPEN = 0)
5 4096_FS 4096xFs (for MLBPEN = 0)
6 6144_FS 6144xFs (for MLBPEN = 0)

Bit 0 – MLBEN MediaLB Enable

ValueDescription
0 MediaLB peripheral is disabled
1 MLBCLK (MediaLB clock), MLBSIG (signal), and MLBDATA (data) are received and transmitted on the appropriate MediaLB pins.
